The invention relates to parallel connection modes and a control method of a hybrid electric vehicle, the parallel connection modes comprise an engine and four clutches in a 4DHT gearbox, four parallel connection modes are formed, and under the four parallel connection modes, the torque of the optimal torque working point of the engine is taken as the center, and the four parallel connection modes are located in the optimal torque working interval range of the engine. According to the technical scheme, based on the hybrid power P2.5 + P4 configuration, the target gear management method under various whole vehicle working modes is designed, the efficient and feasible target gear management method is provided for whole vehicle target gear management and control and some component failure states, and the whole vehicle has the clear target gear management method.

    本发明涉及一种混合动力汽车并联模式及控制方法,其并联模式包括发动机、4DHT变速箱中的4个离合器,组成4种并联模式,在这4种并联模式下,均以发动机最优扭矩工作点扭矩为中心,且位于发动机最优扭矩工作区间范围内。本技术方案基于此混动P2.5+P4构型,设计了具备多种整车工作模式下的目标挡位管理方法,为整车目标挡位管控及一些部件失效状态下提供了一种高效且可行的目标挡位管理方法,让整车具备清晰明了的目标挡位管理方法。
